With a magnet arrangement for an electromechanical drive with a cylindrical armature guided in a pole tube, the position of the armature is transformed into an electrical signal. Provided for this is a displacement sensor which is connected to the armature and has a fixed part and a movable part. One side of the armature is formed such that it transfers the movement of the armature, and the other side of the armature is connected to the movable part of the displacement sensor. The pole tube is provided with a closure part on the side of the displacement sensor. A pressure tube is led to the outside through an axial clearance of the closure part. The movable part of the displacement sensor moves in the pressure tube. The pressure tube is enclosed by the fixed part of the displacement sensor. In order to prevent the displacement sensor from being damaged by vibrations, the fixed part of the displacement sensor is arranged in a clearance of the closure part. Such type magnet arrangements of this type are preferably used for electrical position feedback in fluidic valves.

The invention claimed is: 1. A magnet arrangement for an electromechanical drive, especially for a fluidic valve, with a cylindrical armature guided in a pole tube and with a magnetic coil enclosing the pole tube and with a displacement sensor which transforms the position of the armature into an electrical signal and has a fixed part and a movable part, in which arrangement one side of the armature is formed for transferring the movement of the armature and an other side of the armature is connected to the movable part of the displacement sensor, the pole tube being provided with a closure part on a side of the displacement sensor, wherein the fixed part (28a to 28c, 36; 28a to 28c, 69) of the displacement sensor is arranged in a clearance (24) of the closure part ( 13; 50; 67; 87; 100). 2. The magnet arrangement as claimed in claim 1, wherein a terminating part (25; 51; 68) is held on the closure part (13; 50; 67; 87; 100). 3. The magnet arrangement as claimed in claim 2, wherein electrical connecting lines (63, 64) of the displacement sensor are led through the terminating part (51). 4. The magnet arrangement as claimed in claim 2, wherein a connector (26) is integrated into the terminating part (25; 68; 101). 5. The magnet arrangement as claimed in claim 2, wherein the terminating part (25; 51; 68) is provided with a clearance (27; 70), which goes over into the clearance ( 24) of the closure part (13; 50; 67). 6. The magnet arrangement as claimed in claim 5, wherein a printed circuit hoard (39) is arranged in the clearance (27; 70) of the terminating part (25; 51; 68; 101). 7. The magnet arrangement as claimed in claim 6, wherein the printed circuit hoard (39) is held on terminal pins (41, 42) of a connector (26). 8. The magnet arrangement as claimed in claim 1, wherein the movable part (20) of the displacement sensor is guided in a pressure tube (29; 53). 9. The magnet arrangement as claimed in claim 8, wherein the pressure tube (29; 53) is provided with a collar (30; 54), which is supported on an annular face (31), facing the armature (12), of the closure part (13; 50; 67; 87; 100). 10. The magnet arrangement as claimed in claim 9, wherein the collar (54) is formed as a guide (55) for a spring ( 19) arranged between the armature (12) and the closure part (50; 67; 87). 11. The magnet arrangement as claimed in claim 1, wherein the closure part (13; 50; 67; 87; 100) is provided with an external thread (18), an outside diameter (d 18) of which is smaller than the outside diameter (d11) of the pole tube (11). 12. The magnet arrangement as claimed in claim 2, wherein the terminating part is made of plastic and molded onto the closure part ( 87). 13. The magnet arrangement as claimed in claim 2, wherein the fixed part (28a to 28c, 36) of the displacement sensor is held on the terminating part (101), and the terminating part (101) is settable with respect to the closure part (100) in axial direction. 14. The magnet arrangement as claimed in claim 13, wherein the terminating part (101) is connected to the closure part ( 100) by a screw drive (104, 105). 15. The magnet arrangement as claimed in claim 14, wherein the closure part (100) is provided with an internal thread ( 104) and the terminating part (101) is provided with an external thread (105). 16. The magnet arrangement as claimed in claim 13, wherein securing means (108) which prevent unintentional turning of the terminating part (101) with respect to the closure part (100 ) are provided. 17. The magnet arrangement as claimed in claim 16, wherein the terminating part (101) is provided with a check nut (108 ), an internal thread (107) of which is supported on an external thread (105) of the terminating part (101) and an end face (110) of which, facing the closure part (100), is supported on the latter.
